Downhill champion and all-'round wizard Fabien Barel made this nice little instructional video on all-mountain riding that includes sections not only (of course) on cornering, braking, etc. but jumps and drops too. Nice in-a-nutshell that really could benefit any rider, IMO.
When you have a half-hour free to watch something, give it a spin:
Side note: The helmet Fabien is wearing is an Urge Enduro-O-Matic. I love mine.
